Abstract
Resveratrol (3,5,4'-trihyidroxystilbene) is a natural phenolic compound, which belong to phytoalexins. It is found in many plants, such as mulberry, peanut and grapes. Increasing interest in monitoring the presence of resveratrol in wine was caused by its role on human health. Recent studies have proved that this substance, cause of its antioxidant action, inhibits the oxidation of low-density lipoproteins (LDL), reducing the risk of miocardiac disease and arteriosclerotic pathologies. It has been also demonstrated that this substance inhibits cellular events associated with tumor initiation, promotion and progression, reduces cell death from oxidative stress, inhibits platelet aggregation and eicosanoid synthesis, and prevent anti-inflammatory activity. The aim of this report is to develop innovative chromatographic methods, using miniaturized chromatographic systems to characterize and to determinate the stilbene levels in red wine samples from the Lazier area, resulting from different cultivars, representative of testing zoneI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
